ÑuSAT-1 , Fresco , Aleph 1-1 , LO-87 or LUSEX OSCAR 87 is an Argentine earth observation satellite that carries an amateur radio payload called LUSEX. After a successful start, the satellite was assigned the OSCAR number 87.

mission

The satellite was launched on May 30, 2016 together with its sister satellite ÑuSAT-2 on a CZ-4B rocket together with the main payload Ziyuan 3-2 from the Taiyuan Cosmodrome. Immediately after the launch, strong signals from both satellites could be received in the Bariloche ground station . ÑuSAT-1 is the first satellite of the commercial earth observation program Aleph 1 , in which real-time images are to be offered continuously. Up to 300 satellites are planned for the further expansion of the Aleph program (as of 2016). The satellite is developed and operated by Satellogic SA. The camera equipment consists of a monochromatic camera, a multispectral camera, a TIR infrared camera and a video camera.

Amateur radio

LUSEX stands for LU Satellite EXperiment , where LU is the ITU prefix is Argentine callsign . LUSEX consists of a linear transponder for mode U / V, which was built by AMSAT-LU . The linear transponder is located on a circuit board measuring 10 cm × 10 cm, has a bandwidth of 30 kHz and a transmission power of 250 mW. The transponder works via a dual band antenna for the 70 cm and 2 m bands .

Frequencies
